Answer 1

您可以使用

bricks = pygame.sprite.Group()
bricks.add( Bloque(0, 0) )
bricks.add( Bloque(100, 0) )
# etc.

保持砖块。

稍后你可以使用

bricks.draw(screen)

bricks.update() 

pygame.sprite.spritecollide(bola, bricks, dokill=True)

你需要建立一个约束，这样只有当X值介于0和??（最大宽度）之间时它才会移动。

for event in pygame.event.get():
    if event.type == pygame.QUIT:
        sys.exit(0)
    elif event.type == pygame.KEYDOWN:
        if event.key == K_LEFT and barra.rect.centerx > 0: # Set your minimum value
            barra.rect.centerx -= 20
        elif event.key == K_RIGHT and barra.rect.centerx < 100: # Set your maximum value
            barra.rect.centerx += 20
        elif event.key == K_ESCAPE:
            sys.exit(0)
    elif event.type == pygame.KEYUP:
        if event.key == K_RIGHT:
            barra.rect.centerx += 0
        elif event.key == K_LEFT:
            barra.rect.centerx += 0

当然，您应该添加或减少条形宽度等内容。试试这些价值观。

在边缘你应该添加像

这样的东西

barra.rect.centerx -= (difference between left edge and bar)

barra.rect.centerx += (difference between right edge and bar)
